E32-900T20D communication

How to configure Ebyte E32-900T20D modules? Ebyte tool “RF Setting E32 TTL v3.49” does not work ("Module not supported" message).... I tried also LittleFS, following the instructions on http://mischianti.org/ebyte-lora-e32-web-manager-description-configure-and-demo-esp8266-esp32-2/ but when I refresh the configuration website, I get different configuration and moduleinfo data every time. Also a message "The information on the module is inconsistent, reset the device." I can easily establish communication between E32-868T20D modules. Is there a difference in approach between E32-868T20D and E32-900T20D modules? Best regards, Rudy
